It can be switched on and off by the INH pin. It is functional compatible to the TLE 4266, but with a reduced quiescent current of << 1 µA in OFF mode and 40 µA in ON mode. The TLE 4266-2 is especially designed for all applications that require very low quiescent current in ON and OFF mode. The device is available in the small surface mounted PG-SOT223-4 package. It is pin compatible to the TLE 4266 G. It is designed to supply microprocessor systems under the severe condition of automotive applications and therefore it is equipped with additional protection against over load, short circuit and overtemperature. Of course the TLE 4266-2 can be used in other applications, where a stabilized voltage and the inhibit feature is required. And input voltage V up to 45 V is regulated to V = 5 V (TLE 4266-2 G) or V = 3.3 V I Q Q (TLE 4266-2 GSV33) with an accuracy of ±3%. For the 5 V device an accuracy of ±2% is kept for a load current range up to 50 mA. The device operates in the temperature range of T = -40 to 150 °C. A High level at the j INH pin switches the regulator on. Type Package TLE 4266-2 G PG-SOT223-4 TLE 4266-2 GSV33 PG-SOT223-4 Data Sheet 1 Rev. 1.4, 2008-03-10

The regulation loop controls the output to achieve an output voltage of 5 V with an accuracy of ±2% at an input voltage up to 45 V. The minimum required input voltage is V + V with a drop voltage V of max. 0.5 V (see “Typical Performance Q dr dr Characteristics” on Page 8) in case of the TLE 4266-2 G. The TLE 4266-2 GSV33 requires a minimum input voltage of 4.4 V. The TLE 4266-2 can supply up to 150 mA. However for protection reasons at high input voltage above 25 V, the maximum output current is reduced (SOA protection). Figure 3 shows a typical measuring circuit. For stability of the control loop the TLE 4266-2 output requires an output capacitor C of at least 10 µF with a maximum Q permissible ESR of 4 Ω. Tantalum as well as multi layer ceramic capacitors are suitable. At the input of the regulator an input capacitor is necessary for compensating line influences (100 nF ceramic capacitor recommended). A resistor of approx. 1 Ω in series with C, can damp any oscillation occuring due the input inductivity and the input I capacitor. In the measuring circuit shown in Figure 3 an additional electrolytic input capacitor of 470 µF is added in order to buffer supply line influences. This capacitor is recommended, if the device is sourced via long supply lines of several meters. The TLE 4266-2 includes the Inhibit function. For a voltage above 3.5 V at the INH pin the regulator is switched on. Data Sheet 7 Rev. 1.4, 2008-03-10
